? Tree

My hubby brought me in a beautiful bouquet of flowering branches yesterday.  We have no idea what kind of tree it is but I love it and my husband hates it.  Our son in law had cut down one of these for my husband when we first moved in (while I was away).  And so I am sticking to my guns about keeping this one. :)

The tree in question, isn't it pretty when it is flowering. We know it is not a crab apple tree.   But from there it is any ones guess.
